COPYING-MACHINE Specification of Letters Patent.

Patented Oct. 29, 1907.

Application tiled April 15| 1907. Serial No. 368.397.

To all Iwhom it may concern: n

e it known that l, Finnonrcn SonNNucKnN, a subject oi the King ol` Prussia7 German Emperor7 and a resident ot Bonn-on-the-lthine. German Empire7 have invented certain new and uselul Improvements in (.opyiiigh'lacliiiit\s, olE which the i'ollowing is an exact' specilieation.

My invention relates to an improved copying machine which permits ol a continuous paper-band to be divided into single sections without using any cutting apparatus.

ln the known copying machines having a continuous paper band there is a great diileulty in dividing the paper' into single' sheets by a cutter alter copying has taken place. The wet and thin copying paper' does not permit to be cut safely during a longer time and in cutting the paper in a dried condition there is a considerable loss ol time by rendering straight and smooth the paper which has previously become curled up.

According to the present invention the disadvantage is avoided by subjecting the continuous paper band to tension, the paper band being weakened or rendered less res It is attained thereby that the paper band is torn at those places without using the objectionable cutting process.

ant at single spots.

lt is well known to use continuous paper' bands having spots which are rendered less resistant, as l'or instance in rotation-machines, and copying presses, but heretofore it has not been subjected to a mechanical tension process. The considerable advantage resulting therelirom will be obvious and the unlimited einploymeut ol' continuous paper-bands in copying niachines is insured thereby and at the same time the objectionable cutting operation is perlectly dispensed with.

For having the paper band taut or stretched and separating thereby the latter at the spots less resistant, the paper written upon is caused to be caught for iustance by a roller pair, whereas at the same time the paper band is between rollers being opposite to the Iirst mentioned rollers or otherwise conveniently arranged. ll now this pair ol rollers is put into a quicker revolution than the other rollers, tension is produced and the paper band torn oil' at the spot less resistant.

Instead oi tension-rollers, graspers or similar acting means can be provided. The separation can be eliected in a modified manner thereby that the paper baud is kept taut only whereas a rail or the like is Iorced laterally against or transversely upon the paper, whereby the latter is taut or stretched thus that separation takes place.

ln order to make my invention more clear7 l reier to the accompanying drawing, in which:

Figure l. shows a side view. and llig, 2 a plan.

In the ligures a illustrates the supply roller upon which the paper baud having single weakened 0r less resistant spots is wound. The paper on this roller is in a dried condition.

b is a roller intended for moistening or dampening the paper starting `from the supply roller a; c d represents a pair ol' rollers by means o which the paper is squeezed aiter its moistening.

c is a roller which cooperates with the roller c Ior providing the paper band s with the writing and copy respectively, in that the paper to be copied is introduced between these rollers.

It is a leeding band to which the copying paper is conveyed by means ol the roller f.

f/ lL is a pair oi rollers between which the paper is guided by said feeding band k. ,lhe roller g is in communieatitiin with the roller c by any pulling organ, as [or instance a chain 'ni (diagrammatically shown). The arrangement must be provided thus that the roller g is rotated more quickly than the roller c.

'lhe operation oi' the machine as loregoing described will be obvious. The paper band starting from the supply roller a and rendered less resistant at single places l'or inst-anco by perlorations is nioistencd by the roller b and is introduced when squeezed between the rollers c and c, for making the copy. The paper band is then conveyed to the stretching rollers g h by means ol the l'eeding band k in such manner that the paper band is caught by the rollers g h when a less resistant or perlorated place has just passed through the rollers c c. As the rollers g h revolve more quickly tension is produced in the copying paper' and separation thereby takes place at the perforated place.

lt will be observed that the foregoing described copying machine will be understood as an example only and that modiiications can bc provided in different directions, without departing from the essence oi my inventiony which consists in making the copying paper which is provided with weakened or less resistant places, to be subjected to tension whereby separation takes place at the alorementioned place.

Having thus fully described the nature 0i my inventiony what l desire to secure by Letters Patent oi the VUnited States isz- 1. In a copying machine or press, working upon a continuous paper band, which is weakened or rendered less resistant at various places, means for producing tension in the paper band thereby dividing or tearing 011:" the paper hand at the places less resistant.

2. A copyingl machine or press, comprising a supply roller journaled in the machine standard and having wound on to it a continuous paper' band having:r weakened or less resistant places, a nioistening roller over which the c0ntinuous paper band is guided [or its moistening or darnponing, squeezing rollers between which the paper' band passes, pressure rollers for providing the paper band with copies, rollers catching the paper hand when the copies are made, and means for operating the catching rollers thus that they revolve more quickly than the pressure rollers.

3. A copying machine or press, comprising a supply roller journaled in the machine standard and having Wound ou to it a continuous paper band having weakened or less resistant places, a moistening roller, over which the continuous paper band is guided for its moistening, squeezing rollers between which the paper band passes, pressure rollers for providing, the paper hand with copies, a feeding band receiving the paper band, when copies are made, rollers catching the paper band fed by the feeding band,

and a pulling organ connecting a pressure roller and a catching roller in such manner that the catching rollers revolve more quickly than the pressure-rollers.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
